FURNACE Application filed July 26, 1905. Serial No. 271,374.

To all @7mm it moy concer-n:

it lino-wn that l, MAX Birrnien, citizen of the German Empire, residingat present et Milan, italy, have invented. certain new and usefulimprovements in Yllinnacesg and l do he l v c the following to be afull, und exact lescription oi the invention, enable others skilled inthe art to uppcrtains to inaiie and use the This inventitui relates aregenerator for retort-ovens and other furnace systems with regenerativetiring, and has for its object to transmit the load 'pr esule, producedbythe erts or other par or" the oven located in the upper portion ci theregenerator charnr, to vfoundatituis, partly through the verticaldivision Walls between the air and as 'lines the rcgenerator, whichwalls act s support g pillars. For this purpose the irision walls of thelines are built of plates set tirectly one upon the other edgewise. Atthe sarne time, in this Way the building of the regenerator is inadeeasier.

ln the drawing is shown, as an example of the manner of carrying out theinvention, a retort oven with a regenerator, in which drawing-- Figure 1shows a retort oven one-half in elevation and the other half in verticalsec tion on the line l--l ot' Fig. 2. 'ltig. 2 shows e vertical sectionon the line 2e-2 of Fig. l Fig. 3, a cross section on the line 3 3 ofFig. 2; Fig. fr, a detail perspective view of a part ot" l leregenerator on an enlarged scale; and l? e, of the pla 'frein which thelines of the regenerater may he built.

The retort oven shown is provided in; the' known manner *with a niiddlegenerator a. trein which the enerator gas flows through the 'lines orducts b into the upper chamber of the oven which contains the retorts c,the gas mixing 'with the air oi3 combustion entering throughtl'xepassage or llue d, and heated in the regenerator.

lne oren is ouilt symmetrically and has a. regene" or at cach side, eachof which consists ct, o .Groups ol ihres, each group cornprising nseries oi ilucs lying one above the other, one up serving .for theintroduction the air et combustion, the other for drawing oli the iiregases, that is, the gaseous products of combustion;

The lines e for the air of 'combustion are locate( `upon the inner side,next to the gensiinilar vieu' oi a inodiiied orrn l Specification ofLetters Patent.

products of combustion, is done by nieans of t vertical piller-likedivision Walls, while the individual dues, lying one above the other,are separated from one another by horizontal cover platos.

rlhe vertical division Walls consist of plates g, which are placededgewise directly upon one another, and each uall is formed of tuostrata of plates laid closely against each other. The individual plates,as best shown in Fig. 4, are provided on the outer sides withbracket-like bearings h, upon uhich rest horizontal flue cover- )latesi, 'lhe upper supporting surfaces of t e bearings, li, are of such aheivht that tongues, z/

l are left on the plates above the bearings, LMSD which tongues form ashoulder or stop against uhich the edges of the cover-plates 'i Y rest.The lowest plates g stand in grooves 7c formed in the oven bottom, andthe heights of the bearings h are such in proportion to the thickness ofthe plates t, that the said cover-plates i when in place `will lie `withtheirl upper surfaces above the upper` edge of thecorresponding,vertical plate g,

uhereby the cover- )lates tV support the vertical plates g, laterallythe said plates having lou er vertical surfaces at h2, as shown. Uponthe oven Wall of the regenerator opposite the hearings 7L, are locatedfixed bearY ings l for the cover plates i. The plates or tiles ol" whichthc vertical division Wallstare huilt up thus have the followingcharacteristics: 'lhev have a flat surface extending' the vrhole lengthof the plate, along which surface the plates of tao adjacent vertical10| strata are placed into contact with one another. The side of theplate opposite the flat surface is provided u ith a bracket-like or\'-.c(,lge-shaped hearing, h, forniing a shelf at its top, which bearingoccupies a position 10 intermediate the ends ci the plate or tileandleaves a tongue, it', at the upoer end and a portion, h2, at thelower en Whose surface is substantially parallel lto the opposite fiatvsurface. The shelf, tongue h and 11 surface las extend entirely acrossthe plate. 'lhevertical plates g are handed together the air ofcombustion and the o0 by arranging the two strata of plates to breakjoints verticali thus preventing leakage through the wals. For thispurpose it is advisable to make end plates g (Fig. 4) of one-third thewidth of the main plates, these end' plates being placed in therespective horizontal series of plates in such a manner that one suchplate g', is located at one end of one row in one stratum of plates andanother end plate g at the opposite end of the corresponding row of theother stratum of plates. In this way the plates of the two strata havetheir joints displaced to an extent equal to the width of one end plate.

The packing of the horizontal joints between the vertical plates is doneby the cover-plates i, as will be clear from the drawings, since theseplates cover said join ts. No especial means is requisite for packingthe joints between the respective cove-rplates, as the air of combustionand the urned gases iiow side by side and are perfectly separated by thevertical division wall` bviously any number of air fines and draft maybe arranged side bv side in the same manner, whereby the number ofvertical division walls are correspondingly increased. Also, thedivision walls ma be made of more than two strata of plates.

In Fig. 5 is shown another form of plate g2, which may be. employed informingI the vertical division walls, this plate being shou n asprovided with ribs r, \.hich cross each 'other and serve to strengthenthe late. In other respects this plate or tile is t 1e same in substanceas that shounl in the preceding figures., that is, it has anintermediate bearing L, forming a shelf and leaving a tongue, 7iextending above the bearing to a height less than the thickness of thccover plates, i, and a lower surface 7a2 substantially parallel to theflat back surface. In this case again the shelf, tongue 7L and lou ersurface h2 extend entirely across the plate or tile.
